According to It's On The Grid, it just may be on the way. They state that the premise is...aliens who were put on Earth as sleeper cell aliens to eventually call back their race to take over the planet. Ultimately, the group of aliens fully assimilates and don’t want to cause war.
Uh....OK.
The Inhumans (created by Stan Lee and Jack Kirby) are a race of superbeings who live on the dark side of the Moon; they were created by the alien Kree millions of years ago in experiments on primitive humans.
With the possibilities of Skrulls being introduced in the Avengers movie, who knows what's up next. I'm still waiting on news for a Captain Mar-vell movie. :)
